Description
Technical field the present invention relates to the system equipment of intelligent meter data recording system, particularly the dilatation of the concentrator of the main access device of intelligent meter data recording system.
Background technology intelligent meter data recording system equipment comprises main access device and middle routing device.An access point generally connects a main access device only, can connect a plurality of middle routing devices and table.Be limited to the consideration of main access device hardware designs and software design, but the storage list data can not be accomplished infinity, are generally 1983 tables, minority can reach 3900 tables.Occasion such as copy at central three meter transcribing even five table collection, and super large residential quarter such as 10,000 families, 100,000 families, generally need to select a plurality of main access devices, increased user's equipment cost on the one hand, prior, because upstream Interfaces such as phone generally have monthly rental, utilance is not high at ordinary times, arrange resources such as many telephone wires if desired, monthly rental will rise to a very big numeral, and the unnecessary burden that often becomes the user that seems.Though the scheme of principal and subordinate's cascade is arranged at present, how immature, and also its master concentrator also comprises the function of acquisition tables data and storage list data except comprising up external interface, and concept is relatively more chaotic, brings the instability of the high of cost and operation after the circuit complexity.From now on along with the deep development of intelligent meter data recording cause, the multilist collection copy with the super large residential quarter after the problem of checking meter of table number of huge capacity must float the water surface, press for the upgrading that new design concept supports this intelligent meter data recording of concentrator master access device, the scale development that promotes the intelligent meter data recording industry.
Summary of the invention the objective of the invention is to design that a kind of realization is simple, principle is advanced, make up the concentrator of principal and subordinate's cascade flexibly.
The present invention is that the technical scheme that adopts that achieves the above object is: design a kind of principal and subordinate's cascade concentrator, comprise a master concentrator and several from concentrator, realize huge dilatation by principal and subordinate's cascade.Respectively can concurrent work from concentrator, distinguish mutually by address code, save the time of acquisition tables data.Each master concentrator has 4 tunnel outputs, and the output of every road can connect 32 from concentrator; Each can store 8127 table data at most from concentrator.Can store 128*8127=1040256 at most from concentrator for 4*32=128 and show data, therefore, principal and subordinate's cascade can realize the huge dilatation of concentrator.An access point connects a master concentrator only, but can connect maximum 128 from concentrator.Master concentrator provides upstream Interfaces such as phone, GPRS, CDMA, and transparent channel only is provided, not acquisition tables data, storage list data not, no timing acquiring function.Do not have directly external upstream Interface from concentrator, only by cascade RS-485 bus interface master concentrator, but but from concentrator acquisition tables data storage list data, the timing acquiring function is arranged.
Description of drawings
Fig. 1 be master concentrator of the invention process with from concentrator cascade schematic diagram.
The invention will be further described below in conjunction with drawings and Examples for embodiment.
A kind of principal and subordinate's cascade concentrator adopts master concentrator and realizes dilatation from the compound mode that concentrator is arranged in pairs or groups.
The present invention is by the master concentrator external interface, by USB, RS-232, phone, GPRS, CDMA, WIFI, Ethernet, infrared etc. and far-end or local computing communication.
Behavior four road cascade bus provide transparent channel under the master concentrator, and every road can connect 32 from concentrator.
Because RS-485 is relatively flexible way of half-duplex, so cascade bus is selected the RS-485 bus for use.
Master concentrator only provides transparent channel, not acquisition tables data, storage list data not, no timing acquiring function.Therefore master concentrator is not considered memory circuit, clock circuit etc., and necessarily cost reduces cost, and certainly, the cascade bus circuit of increase also is very complicated, can increase material cost and processing cost to a certain extent.Substantially we can say that master concentrator is basic suitable with conventional concentrator complexity, but design concept is more advanced.
Be the actual functional capability unit from concentrator.Its up original external interface is cancelled, and replaces cascade bus, can receive on the down going channel of master concentrator by cascade bus, by the upstream Interface of master concentrator data is passed to far-end or local computing.
But but from concentrator acquisition tables data storage list data, the timing acquiring function is arranged.
Comprise memory circuit, clock circuit from concentrator.Will connect table or connect table by routing device in the middle of connecing owing to descending, because the relay function of isolation and function of supplying power need be arranged, and assurance can connect equipment as much as possible, connects table more, connects equipment at a distance, connect table at a distance in design.
As shown in Figure 1, four road cascade bus of a master concentrator output are respectively cascade bus 1, cascade bus 2, cascade bus 3, cascade bus 4.Can only use wherein any one road cascade bus, perhaps use the multichannel cascade bus to connect from concentrator.Every road cascade bus is recommended to connect 32 from concentrator, is respectively from concentrator 1,2 to n.
Because the external interface type is numerous, only need replace a master concentrator by principal and subordinate's cascade, can realize that all external interfaces from concentrator are replaced, reduce interface cost, especially reduce monthly rental.
And because system equipment and table have RS-485 and MBUS two big series, by principal and subordinate's cascade, from the descending of concentrator or be RS-485, or be MBUS, and also having only two kinds from the model of concentrator like this, type kind is controlled, is convenient to get ready the goods and production.
And, after principal and subordinate's cascade, can concurrent work from concentrator, carry out data acquisition simultaneously.As everyone knows, data acquisition is a very long wait process, needs calculate in 0.5 second by each table collection, and 8000 tables are exactly 4000 seconds, are exactly 67 fens kinds, surpass 1 hour, and the time is very very long.By parallel work-flow, can save user's quality time.
Further be, even single concentrator, capacity is also compared 1983 general tables of industry have been increased more than maximum four times, and 8127 tables are the time of checking meter and the proper compromise of capacity of checking meter.
From concentrator owing to there is not special-purpose external interface, save expensive outsourcing module cost, therefore cost of equipment also can reduce, and especially for surpassing two schemes from concentrator, takes principal and subordinate's cascade obviously to select on a plurality of conventional concentrator availabilities and the double dominant on the price than simple.
In a word, the scheme of principal and subordinate's cascade concentrator combination is the more satisfactory mode of cell capacity-enlarging.
Principal and subordinate's cascade concentrator still urgently even is not expected in current needs, but following deep development along with policy promotion intelligent meter data recording causes such as reading the ammeter directly, the problem of checking meter of the table number of huge capacity must become a difficult problem that needs solution.If problem solves thus, must become and support remodeling and the huge thrust of industry development of intelligent meter data recording master access device, because the present invention has very high market value and good social effect.
